    Adds reproducer check+exit+warning dependencies - virtualenv+others

    Running reproducer fails if you don't have python-virtualenv installed.
    This adds a check and warning which is nicer than the usual error
    "reproducer-quickstart.sh: line 199: virtualenv: command not found"

    After discussion also added check for pip and further testing also
    showed the need for ansible and openstackclient.
